Description

Technical Field

[0001] This application relates to the technical field of children's products, and in particular to a folding crib. Background Technology

[0002] Baby cribs are a common children's product used as children grow. Sleeping in a crib can help young children develop independence and reduce their dependence on their parents. In addition, cribs can provide a safe play area for young children and prevent accidents such as falls and drops.

[0003] However, the current market offers an overly complex array of cribs categorized by type and applicable scenarios. This forces consumers to purchase multiple cribs as their children grow. Specifically, newborns aged 0-5 years require a crib that can be placed next to an adult bed; children aged 2-5 years need a larger wooden bed; playpens can enclose young children for short periods of independent play; and portable cribs are easy to fold and unfold. On the one hand, too many subcategories can cause choice anxiety for consumers, affecting the user experience. On the other hand, purchasing too many different cribs not only increases operating costs but also takes up a significant amount of indoor space. Summary of the Invention

[0004] Therefore, it is necessary to provide a folding crib to address the issues of time-consuming and labor-intensive installation, potential damage risks, and inconvenience in use, storage, and carrying when going out.

[0005] This application provides a folding baby crib, which includes:

[0006] The first bed assembly includes a first support, a first upper rail and a first lower rail, the first end of the first upper rail and the first end of the first lower rail are rotatably connected to the first support, and the first upper rail and the first lower rail can rotate and fold in opposite directions;

[0007] The second bed assembly is disposed opposite to the first bed assembly. The second bed assembly includes a second support, a second upper rail and a second lower rail. The first end of the second upper rail and the first end of the second lower rail are rotatably connected to the second support, and the second upper rail and the second lower rail can rotate and fold in opposite directions. The second end of the first lower rail is rotatably connected to the second end of the second lower rail.

[0008] The locking mechanism is rotatably connected to both the first upper frame rod and the second upper frame rod, and can lock or unlock the first upper frame rod and the second upper frame rod to switch the folding crib between an unfolded state and a folded state.

[0009] A bed board mechanism, rotatably mounted on the first lower support rod and the second lower support rod, and capable of switching between a supported state and a stowed state, the bed board mechanism, together with the first bed assembly and the second bed assembly, forms a receiving space; and

[0010] A sleeping bed, which is movably disposed on the first bed assembly and / or the second bed assembly, wherein when the folding crib is in the unfolded state, the sleeping bed is located inside the folding crib and above the receiving space, and when the folding crib is in the folded state, the sleeping bed is located outside the folding crib.

[0011] The folding crib of this application is sold in an assembled structure form. That is, when the user purchases the folding crib, the first bed component, the locking mechanism and the second bed component are already in the assembled structure state. Therefore, the user does not need to spend a lot of time reading the installation instructions and performing a large number of parts installation operations, which can greatly save the user's physical strength and time, and eliminate the risk of damage to the folding crib due to incorrect assembly.

[0012] Furthermore, when the folding crib is in the unfolded state, the locking mechanism locks the first and second supports, keeping them far apart. At the same time, the first and second upper and lower support rods remain flat and supported, making the folding crib easy to use. At this time, the bed board mechanism is in the unfolded support state, allowing young children to be placed alone in the storage space for a short period, providing a play area for them and freeing adults to do other things. The bed can also be installed above the storage space and inside the folding crib, allowing infants to sleep without worrying about them falling to the ground and causing accidents.

[0013] When the folding crib needs to be stored or taken out, simply switch the locking mechanism to the unlocked state. Then, rotate the first upper and lower rails and the second upper and lower rails in opposite directions to fold it up. The first and second supports will also move towards each other simultaneously, allowing the crib to fold into a square structure. At the same time, the bed board mechanism will switch from the supported state to the folded state. The crib can also be quickly and easily adjusted to the outside of the crib by flipping it over, avoiding interference with the folding process. Thus, the folding crib in its folded state is compact, small in size, and occupies little space, making it convenient for storage or carrying. The folding crib is simple, convenient, and effortless to operate, significantly improving the user experience. In summary, this folding crib, when unfolded, provides multiple functions for young children, including sleeping, short-term safe placement, and play. This effectively avoids consumers needing to purchase multiple cribs of different types, reducing costs, minimizing indoor storage space, and eliminating choice anxiety for consumers, thus enhancing the product experience.

[0014] The technical solution of this application will be further described below:

[0015] In one embodiment, both the first and second supports are provided with crossbars. The bed includes a bed frame, a mattress, a fixed clamp, and a movable clamp.

[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] See Figures 1 to 2 This application illustrates a folding crib 100, comprising a first bed assembly 10 and a second bed assembly 20. The first bed assembly 10 and the second bed assembly 20 are arranged opposite to each other in a symmetrical manner, meaning that the first bed assembly 10 and the second bed assembly 20 have the same structure and shape, which helps to reduce the design and manufacturing difficulty and cost of the folding crib 100.

[0045] Specifically, the first bed assembly 10 includes a first support 11, a first upper rail 12 and a first lower rail 13. The first end of the first upper rail 12 and the first end of the first lower rail 13 are rotatably connected to the first support 11, and the first upper rail 12 and the first lower rail 13 can be rotated and folded in opposite directions.

[0046] The second bed assembly 20 includes a second support 21, a second upper surround rod 22, and a second lower surround rod 23. The first end of the second upper surround rod 22 and the first end of the second lower surround rod 23 are rotatably connected to the second support 21, and the second upper surround rod 22 and the second lower surround rod 23 can be rotated and folded in opposite directions. The second end of the first lower surround rod 13 is rotatably connected to the second end of the second lower surround rod 23.

[0047] Specifically, the first upper frame rod 12 is spaced above the first lower frame rod 13, and the second upper frame rod 22 is spaced above the second lower frame rod 23. When the folding crib 100 is folded up, both the first upper frame rod 12 and the second upper frame rod 22 rotate downwards, while both the first lower frame rod 13 and the second lower frame rod 23 rotate upwards. The folding crib 100 in its unfolded state has a cubic shape.

[0048] Furthermore, in this application, there are two of each of the first upper surround rod 12 and the second upper surround rod 22, arranged side by side at intervals along the width direction of the folding crib 100. The length extension direction of each of the first upper surround rod 12 and the second upper surround rod 22 is consistent with the length direction of the folding crib 100. When the folding crib 100 is switched to the folded state, both the first upper surround rod 12 and the second upper surround rod 22 rotate downwards, thereby realizing that the correspondingly connected first set of first upper surround rods 12 and second upper surround rods 22 rotate and close together from being in the same straight line position.

[0049] Similarly, there are two of each of the first lower support rod 13 and the second lower support rod 23, which are arranged side by side at intervals along the width direction of the folding crib 100, and the length extension direction of each of the first lower support rod 13 and the second lower support rod 23 is consistent with the length direction of the folding crib 100.

[0050] The first upper rail 12 and the first lower rail 13, as well as the second upper rail 22 and the second lower rail 23, are set in a one-to-one correspondence in the height direction of the folding crib 100.

[0051] Please continue reading. Figure 1 and Figure 2In addition, the folding crib 100 also includes a locking mechanism 30, a bed board mechanism 40, and a sleeping bed 50. The locking mechanism 30 is rotatably connected to both the first upper rail 12 and the second upper rail 22, and can lock or unlock the first upper rail 12 and the second upper rail 22 to switch the folding crib 100 between an unfolded state and a folded state.

[0052] The bed board mechanism 40 is rotatably mounted on the first lower frame rod 13 and the second lower frame rod 23, and can switch between a supported state and a folded state. The bed board mechanism 40, together with the first bed assembly 10 and the second bed assembly 20, forms a receiving space. The sleeping bed 50 is movably mounted on the first bed assembly 10 and / or the second bed assembly 20. When the folding crib 100 is in the unfolded state, the sleeping bed 50 is located inside the folding crib 100 and above the receiving space. When the folding crib 100 is in the folded state, the sleeping bed 50 is located outside the folding crib 100.

[0053] Please continue reading. Figure 1 and Figure 2 The size of the sleeping bed 50 is smaller than the size of the main structure of the folding crib 100, which consists of the first bed assembly 10, the second bed assembly 20, and the bed board mechanism 40. This allows the main structure of the folding crib 100 to be used by younger children with larger ages and sizes, while the sleeping bed 50 can be used by younger children with smaller ages and sizes.

[0054] The folding crib 100 of this application is sold in an assembled structure form. That is, when a user purchases the folding crib 100, the first bed component 10, the locking mechanism 30 and the second bed component 20 are already in an assembled structure state. Therefore, users do not need to spend a lot of time reading the installation instructions and performing a large number of parts installation operations, which can greatly save users' physical strength and time, and eliminate the risk of damage to the folding crib 100 due to incorrect assembly.

[0055] Please continue reading. Figures 1 to 4 Furthermore, when the folding crib 100 is in the unfolded state, the locking mechanism 30 locks the first support 11 and the second support 21, keeping them far apart. At the same time, the first upper support rod 12 and the second upper support rod 22, as well as the first lower support rod 13 and the second lower support rod 23, remain in a flat, supported position, making the folding crib 100 easy to use. At this time, the bed board mechanism 40 is in an unfolded, supported state, allowing young children to be placed alone in the storage space for a short period, providing a play area for them and freeing adults to do other things. The sleeping bed 50 can also be installed above the storage space and inside the folding crib 100, allowing infants to sleep without worrying about them falling to the ground and causing a safety accident.

[0056] When the folding crib 100 needs to be stored or taken out, simply operate the locking mechanism 30 to switch to the unlocked state. At this time, operate the first upper rail 12 and the first lower rail 13, as well as the second upper rail 22 and the second lower rail 23 to rotate in opposite directions to fold it up. The first support 11 and the second support 21 can also move towards each other synchronously, and the folding crib 100 can be folded into a square structure. At the same time, the bed board mechanism 40 can also switch from the supporting state to the folded state. Sleeping cribs can also be quickly and conveniently adjusted to the outside of the folding crib 100 by flipping over, avoiding interference with the folding of the folding crib 100. Thus, the folding crib 100 in the folded state has a compact structure, small size, and occupies little space, making it convenient for storage or taking out. The folding crib 100 is simple, convenient and labor-saving to operate, which can significantly improve the user experience. In summary, the folding crib 100 in this solution, when unfolded, provides multiple functions for young children, including sleeping, short-term safe placement, and play. This effectively avoids consumers having to purchase multiple crib products of different types, reducing costs, minimizing indoor storage space, and eliminating choice anxiety for consumers, thus enhancing the product experience.

[0057] Please continue reading. Figure 1 and Figure 2 In one embodiment, both the first support 11 and the second support 21 are provided with crossbars 10a. The bed 50 includes a bed frame 51, a mattress 52, a fixed clamp 53 and a movable clamp 54. The mattress 52 is set with the bed frame 51 and cooperates to form a resting space. The fixed clamp 53 is rotatably set on the bed frame 51 and clamped and fixed with the crossbar 10a. The movable clamp 54 is rotatably set on the bed frame 51 and is detachably clamped and fixed with the first upper rail 12 and / or the second upper rail 22.

[0058] When the folding crib 100 is in the unfolded state, the fixing clip 53 is clamped and fixed to the crossbar 10a, while the movable clip 54 is clamped and fixed to the first upper frame 12 and / or the second upper frame 22, forming the installation and positioning of the bed frame 51. This ensures that the crib receives multi-point support and guarantees the stability of the installation, making it suitable for young children to sleep in. When the folding crib 100 needs to be folded up, the movable clip 54 is removed from the first upper frame 12 and / or the second upper frame 22. Then, using the rotatable connection between the bed frame 51 and the fixing clip 53 as a pivot point, the bed frame 51 is flipped outwards from the folding crib 100. This adjusts the bed frame 51, mattress 52, and movable clip 54 to the outside of the folding crib 100, preventing the first bed assembly 10, the second bed assembly 20, and the bed board mechanism 40 from folding together, ensuring that the folding crib 100 can be quickly and easily switched to the folded state.

[0059] Furthermore, based on the above embodiments, the fixing clip 53 has a rotating hole, and the fixing clip 53 is rotatably connected to the bed frame 51 through the rotating hole. A damping sleeve is provided in the rotating hole, and the damping sleeve makes frictional contact with the bed frame 51; or, the bed frame 51 is provided with a fixing member, and when the crib 50 is on the outside of the folding crib 100, the fixing member is connected and fixed to the first support 11 and / or the second support 21. When the crib 50 is flipped to the outside of the folding crib 100, in order to prevent the crib 50 from rotating randomly during transportation or other movements and affecting normal operation, the crib 50 can be reliably connected and fixed to the first support 11 and / or the second support 21 by means of the frictional resistance generated between the damping sleeve and the bed frame 51 or by means of the fixing effect of the fixing member.

[0060] For example, the damping sleeve can be any type of rubber sleeve, metal sleeve, etc., and the specific type can be flexibly selected according to actual needs.

[0061] Furthermore, in another embodiment, the bed board mechanism 40 is detachably connected to the first lower support rod 13 and the second lower support rod 23, and the bed board mechanism 40 is movable and height-adjustable at different height positions of the first support 11 and / or the second support 21. Depending on the height and age of the young children, consumers (parents, etc.) can disassemble the bed board mechanism 40 and select a suitable installation height before installing it at the desired height position of the first support 11 and / or the second support 21. This allows for flexible provision of different heights of storage space, ensuring that young children placed within the storage space can play safely and reliably.

[0062] For example, the detachable connection between the bed board mechanism 40 and the first support 11 and the second support 21 can be any one of the following, but not limited to, threaded connection, snap-fit ​​connection, magnetic connection, etc.

[0063] Please continue reading. Figure 1 and Figure 2 In one embodiment of this application, the bed board mechanism 40 includes a first plate 41, an intermediate plate 42, a second plate 43, a first mounting bracket, a second mounting bracket, and a rotating bracket 44. The first plate 41 is detachably mounted on the first lower rail 13 via the first mounting bracket, and the second plate 43 is detachably mounted on the second lower rail 23 via the second mounting bracket.

[0064] The rotating bracket 44 is disposed between the first lower support rod 13 and the second lower support rod 23, and one side of the rotating bracket 44 is rotatably connected to the first lower support rod 13, and the other side of the rotating bracket 44 is rotatably connected to the second lower support rod 23. The intermediate plate 42 is disposed on the rotating bracket 44 and is located between the first plate 41 and the second plate 43.

[0065] Please continue reading. Figures 1 to 4When the bed board mechanism 40 is in the supported state, the rotating bracket 44, the first lower surrounding rod 13 and the second lower surrounding rod 23 are arranged horizontally, and the first plate 41, the middle plate 42 and the second plate 43 are arranged horizontally. When the bed board mechanism 40 is in the retracted state, the first lower surrounding rod 13 and the second lower surrounding rod 23 rotate towards each other and fold together, and at the same time, the first plate 41 and the second plate 43 rotate towards each other and fold together.

[0066] By employing a split-structure design for the first plate 41, the middle plate 42, and the second plate 43, and installing them one-to-one with the first mounting frame, the rotating bracket 44, and the second mounting frame, the relative rotation between the first lower support rod 13, the rotating bracket 44, and the second lower support rod 23 enables the bed board mechanism 40 to switch between its supported and folded states, and the folding crib 100 to switch between its unfolded and folded states. This eliminates the need for additional operation of the bed board mechanism 40 when operating the folding crib 100, thus avoiding the drawbacks and problems of cumbersome, time-consuming, and labor-intensive use.

[0067] In one embodiment, one of the first support 11 and the second support 21 is provided with a caster wheel 60 with a foot brake at its bottom, and the other of the first support 11 and the second support 21 is provided with a support foot 60a at its bottom. When the folding crib 100 is in the unfolded state, the support foot 60a can be slightly lifted off the ground, and the freedom of movement provided by the caster wheel 60 allows the folding crib 100 to be moved easily and effortlessly. When the folding crib 100 is placed on the ground for use, or when it needs to be stored in the folded state, the foot brakes on the caster wheel 60 are engaged, and both support feet 60a contact the ground, thus achieving stable placement of the folding crib 100 and improving safety during use.

[0068] The locking mechanism 30 includes a locking block, a locking tongue, a transmission component, and an unlocking handle. The locking block is disposed on one of the first upper rail 12 and the second upper rail 22. The locking tongue is movably disposed on the other of the first upper rail 12 and the second upper rail 22. The unlocking handle is rotatably disposed on the first bracket 11 and / or the second bracket 21. One end of the transmission component is connected to the unlocking handle, and the other end of the transmission component is connected to the locking tongue.

[0069] When the folding crib 100 is in the unfolded state, the locking tongue and the locking block are locked and fixed; when the folding crib 100 needs to be switched to the folded state, the locking tongue is unlocked and separated from the locking block by the unlocking handle and the transmission component.

[0070] In summary, implementing the technical solution of this embodiment will achieve the following beneficial effects: The folding baby bed 100 of this application is sold in an assembled structure form, that is, when a user purchases the folding baby bed 100, the first bed assembly 10, the locking mechanism 30, and the second bed assembly 20 are already in an assembled structure state. Therefore, users do not need to spend a lot of time reading the installation instructions and performing a large number of component installation operations, which can greatly save users' physical strength and time, and eliminate the risk of damage to the folding baby bed 100 due to incorrect assembly; In addition, when the folding baby bed 100 is in the unfolded use state, the locking mechanism 30 is kept in the locked state by means of the locking tongue and the locking block, the first bracket 11 and the second bracket 21 are separated from each other, and the first upper bracket 12 and the second upper bracket 22, as well as the first lower bracket 13 and the second lower bracket 23, all remain flat. The folding crib 100 is designed for easy use. When it needs to be stored or taken out, simply rotate the unlocking handle. This pulls the transmission mechanism, causing it to simultaneously pull the locking tongue, thus unlocking and separating the locking mechanism 30 from the locking block. Then, the first upper arm 12, the first lower arm 13, the second upper arm 22, and the second lower arm 23 can be rotated in opposite directions to fold the crib. Simultaneously, the first support 11 and the second support 21 move towards each other, allowing the crib 100 to fold into a square shape. In its folded state, the crib 100 is compact, small in size, and occupies little space, making it easy to store or take out. The crib 100 is simple, convenient, and effortless to operate, significantly enhancing the user experience.

[0071] In one embodiment, the first upper rod 12 is recessed inward at its second end toward the second upper rod 22 to form a receiving hole, and the locking block is inserted and fixed in the receiving hole so that the locking block can be assembled and fixed with the first upper rod 12.

[0072] The second upper arm 22 is recessed inward toward the second end of the first upper arm 12 to form a receiving channel. The locking tongue is telescopically and slidably disposed in the receiving channel, and the transmission component passes through the receiving channel. The receiving channel provides the space required for the installation and sliding movement of the locking tongue and the transmission component. When the user turns the unlocking handle, the transmission component is pulled by the unlocking handle and slides within the receiving channel, thereby simultaneously pulling the locking tongue back into the receiving channel, separating the locking tongue from the locking block, thus unlocking the locking mechanism 30, and enabling the folding baby crib 100 to be folded.

[0073] Optionally, the transmission component can be any one of, but not limited to, wire rope, chain, hemp rope, etc.

[0074] Specifically, in an optional embodiment, the end of the lock block extending out of the receiving hole is provided with a first locking part, and the end of the lock tongue extending out of the receiving channel is provided with a second locking part. When the lock tongue is locked and fixed to the lock block, the first locking part and the second locking part are engaged to restrict the relative rotational freedom of the first upper rod 12 and the second upper rod 22. When the lock tongue is unlocked and separated from the lock block, the first locking part and the second locking part are disengaged to allow the first upper rod 12 and the second upper rod 22 to obtain relative rotational freedom.

[0075] For example, the first locking part is a first-step structure, with the step groove of the first-step structure arranged vertically downwards (or upwards). The second locking part is a second-step structure, with the step groove of the second-step structure arranged upwards (or downwards). When the locking tongue extends from the receiving channel, the second-step structure can precisely engage with the first-step structure, thereby restricting the degree of freedom of rotation of the first upper arm 12 and the second upper arm 22 in the vertical direction, thus forming a locking effect. This ensures the structural stability of the folding crib 100 in the unfolded state and its safe and reliable use. When the unlocking handle is turned to pull the locking tongue back into the receiving channel via the transmission component, the second-step structure separates from the first-step structure, and the first upper arm 12 and the second upper arm 22 regain their degree of freedom of rotation in the vertical direction. The folding crib 100 can then be folded up and switched to the folded state.

[0076] Of course, in other alternative embodiments, the locking tongue and locking block can also adopt other structures to achieve locking and unlocking cooperation, and can be flexibly selected according to actual needs.

[0077] Furthermore, based on any of the above embodiments, the locking mechanism 30 also includes a lock housing, which is rotatably connected to the first upper surround rod 12 and the second upper surround rod 22. For example, the lock housing is a U-shaped plate structure, which is fastened to the outside of the second end of the first upper surround rod 12 and the second end of the second upper surround rod 22 by means of a U-shaped groove, and is rotatably connected to the second end of the first upper surround rod 12 and the second upper surround rod 22 by pins respectively. However, it should be noted that the two ends of the middle plate of the lock housing, which is used to connect the two side plates, are respectively recessed to form relief grooves. The relief grooves are used to accommodate the first upper surround rod 12 and the second upper surround rod 22 when the folding baby bed 100 is folded down, so as to avoid the lock housing from obstructing or interfering with the first upper surround rod 12 and the second upper surround rod 22.

[0078] The first upper frame rod 12 and / or the second upper frame rod 22 have protruding limiting guide posts on their sides, and the lock housing has an arc-shaped guide groove. The limiting guide posts can be slidably inserted into the arc-shaped guide groove. On the one hand, by means of the limiting guide posts sliding in the arc-shaped guide groove, the first upper frame rod 12 and the second upper frame rod 22 can be limited and guided by rotation and folding, improving the overall structural stability of the folding crib 100 during folding. On the other hand, when the folding crib 100 is in the unfolded and folded state, the limiting guide posts will abut against the two end walls of the arc-shaped guide groove along its length, respectively, to form a positioning effect during shape change, improving the effectiveness and reliability of folding and unfolding.

[0079] Please continue reading. Figure 1 In another embodiment, the folding crib 100 further includes a synchronization mechanism 70, one end of which is rotatably connected to the first support 11, and the other end of which is rotatably connected to the second support 21. The synchronization mechanism 70 is also rotatably connected to the lock housing. The synchronization mechanism 70 ensures that the folding or unfolding movements of the first crib assembly 10 and the second crib assembly 20 are synchronized, improving the user experience.

[0080] Specifically, in the above embodiment, the synchronization mechanism 70 includes a first synchronization rod, a first synchronization wheel, a second synchronization wheel, a third synchronization wheel, a fourth synchronization wheel, and a second synchronization rod. One end of the first synchronization rod is rotatably connected to the first bracket 11, and the other end of the first synchronization rod is fixedly connected to the first synchronization wheel. The first, second, third, and fourth synchronization wheels are all rotatably disposed inside the lock housing and their circumferential surfaces abut against each other in sequence. The fourth synchronization wheel is fixedly connected to one end of the second synchronization rod, and the other end of the second synchronization rod is rotatably connected to the second bracket 21.

[0081] After the locking mechanism 30 is unlocked, when a downward pressing force is applied to the first upper rod 12 and the second upper rod 22, the first upper rod 12 and the second upper rod 22 will begin to rotate downwards. At the same time, the first, second, third, and fourth synchronous wheels remain in close contact and rotate synchronously under the action of friction. This ensures the synchronicity and consistency of the rotation of the first upper rod 12 and the second upper rod 22, so that the first bed assembly 10 and the second bed assembly 20 are tightly fitted together after folding, and the structure is neat and consistent. It is easy to understand that the first and second synchronous rods are used to increase the support force on the four synchronous wheels to ensure that the four synchronous wheels are always in effective rolling contact.

[0082] Preferably, the first, second, third, and fourth synchronous pulleys are all gears. The meshing of the gears can completely eliminate the problem of slippage causing the first bed assembly 10 and the second bed assembly 20 to rotate and fold out asynchronously.

[0083] In one embodiment, both the first bracket 11 and the second bracket 21 are provided with a crossbar 10a. The crossbar 10a has a receiving notch, and a rotating seat is provided on the side wall of the receiving notch. The unlocking handle has a rotating part, which is connected to the rotating seat through a rotating shaft. This allows the unlocking handle to be rotatably connected to the crossbar 10a through the rotating shaft, giving the unlocking handle a degree of rotational freedom so that the user can perform a rotational unlocking operation.

[0084] Furthermore, the unlocking handle is provided with a clearance ramp, which is used to prevent collision and interference with the crossbar 10a when the unlocking handle is turned to unlock.

[0085] In another embodiment, the end of the transmission component used to connect to the unlocking handle is provided with an anti-disengagement buckle, and the unlocking handle is provided with an anti-disengagement groove, in which the anti-disengagement buckle is engaged. The transmission component and the unlocking handle are easy to install, have high connection strength, and can effectively pull on the transmission component when the unlocking handle is rotated.

[0086] In addition, the locking mechanism 30 also includes an elastic element, which is connected to at least one of the latch, the transmission element, and the unlocking handle to provide a reset force. When the locking mechanism 30 is unlocked, and / or the unlocking handle rotates, and / or the transmission element is pulled while the latch retracts, all of which force the elastic element to elastically compress. When the folding crib 100 switches from the folded state back to the unfolded state, after the latch aligns with the locking block, the reset force output by the elastic element causes the unlocking handle to rotate and reset automatically, the transmission element to move and reset automatically, and the latch to extend and reset automatically, thus automatically locking and fixing with the locking block. This improves the automation level of the folding crib 100, saves user operation steps, and enhances the user experience.

[0087] Optionally, the elastic element can be, but is not limited to, one of the following: a spring, an elastic column, or a spring sheet.

[0088] In this application, the crossbar 10a is provided with a mounting groove, the elastic element is installed in the mounting groove, and the end of the elastic element away from the unlocking handle is fixedly connected to the elastic element. When the unlocking handle is operated to rotate to drive the transmission component to slide, the transmission component can force the elastic element to undergo compression deformation.

[0089] In another embodiment, the folding crib 100 also includes a pad disposed on the first lower support rod 13 and the second lower support rod 23. Items can be stored on the pad, which helps to improve the storage capacity of the folding crib 100.

[0090] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0091] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
